DETAILED DESCRIPTION OF THE EMBODIMENTS

Referring to FIG. 1 , there is shown a schematic view of a surgicalmedical device according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 1 , a surgical medical device 100comprises a support portion 110 and a rod portion 120. The supportportion 110 extends from the rod portion 120. The support portion 110has a first stretch segment 114, third stretch segment 115 and secondstretch segment 116. The third stretch segment 115 is disposed betweenthe first stretch segment 114 and second stretch segment 116. Thesurgical medical device 100 has a control mechanism. The surgicalmedical device 100 stretches or contracts the first stretch segment 114,third stretch segment 115 and second stretch segment 116 by the controlmechanism. Preferably, when the first stretch segment 114, third stretchsegment 115 and second stretch segment 116 are each in a stretchedstate, the first stretch segment 114 is of a larger stretched volumethan the third stretch segment 115, and the second stretch segment 116is of a larger stretched volume than the third stretch segment 115. In aspecific embodiment, the support portion 110 is made of a memory alloy.The control mechanism of the surgical medical device 100 is in a plasticstate when the first stretch segment 114, third stretch segment 115 andsecond stretch segment 116 are below a first temperature, and in astretched state when above a second temperature. When the first stretchsegment 114, third stretch segment 115 and second stretch segment 116are in a plastic state and are subjected to a compressing externalforce, the stretched volume of the first stretch segment 114, thestretched volume of the third stretch segment 115, and the stretchedvolume of the second stretch segment 116 decrease. In a specificembodiment, the first temperature is 20 degrees, and the secondtemperature is 35 degrees. In different specific embodiments, the firsttemperature and second temperature are set to any other temperatures asneeded. In different specific embodiments, the temperatures of the firststretch segment 114, third stretch segment 115 and second stretchsegment 116 are controlled by liquid contact or charging; but thedisclosure is not limited thereto.

In the embodiment illustrated by FIG. 1 , the support portion 110comprises support conducting wires 111, 112, 113. The support portiondoes not necessarily have three support conducting wires; instead, thesupport conducting wires may be in any number other than three asneeded. For example, the support portion may comprise two or foursupport conducting wires as needed; but the disclosure is not limitedthereto. In the embodiment illustrated by FIG. 1 , the rod portion 120has a rod end 122, and the support portion has a first support end 117.The rod end 122 and the first support end 117 are connected. The supportportion further has a second support end 118 connected to the rodportion 120. In a specific embodiment, the first support end 117 is anarcuate-shaped arcuate end for preventing the insertion of the firststretch segment 114 into the human body from causing injuries, such asperforation, to the human body. In different specific embodiments, thefirst stretch segment 114, third stretch segment 115 and second stretchsegment 116 of the support portion 110 are of different lengths asneeded, allowing the urologist to determine before surgery what size ofthe applicable surgical medical device is appropriate according tomedical images. The stretched volume ratio of the first stretch segment114, third stretch segment 115 and second stretch segment 116 to eachother in this embodiment serves exemplary purposes and can be adjustedor set as needed. For example, the stretched volume of the third stretchsegment 115 and the stretched volume of the first stretch segment 114can be larger than how they look in FIG. 1 ; but the disclosure is notlimited thereto. The first stretch segment 114 and/or second stretchsegment 116 in a stretched state take on a specific shape (for example,arcuate shape, round shape, and elliptic shape, but the disclosure isnot limited thereto).

Referring to FIG. 2 , there is shown a schematic view of the surgicalmedical device according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 2 , a surgical medical device 200comprises a support portion 210, rod portion 220, and control portion230 movable relative to rod portion 220. A control mechanism of thesurgical medical device 200 is the control portion 230 disposed on therod portion 220. The support portion 210 has a second support end 218.The control portion 230 is connected to the second support end 218. Thecontrol portion 230 moves relative to the rod portion 220 to therebystretch or contract a first stretch segment 214 of the support portion210, a third stretch segment 215 of the support portion 210, and asecond stretch segment 216 of the support portion 210. For example, thecontrol portion 230 moves in the direction 252 relative to the rodportion 220 to thereby stretch the first stretch segment 214, thirdstretch segment 215 and second stretch segment 216. Alternatively, thecontrol portion 230 moves relative to the rod portion 220 in thedirection 254 to thereby contract the first stretch segment 214, thirdstretch segment 215 and second stretch segment 216. Preferably, when thefirst stretch segment 214, third stretch segment 215 and second stretchsegment 216 are each in a stretched state, the first stretch segment 214is of a larger stretched volume than the third stretch segment 215, andthe second stretch segment 216 is of a larger stretched volume than thethird stretch segment 215. In a specific embodiment, the support portion210 has flexibleness, and thus the first stretch segment 214 and secondstretch segment 216 of the support portion 210 stretch or contract whenthe control portion 230 moves relative to the rod portion 220. The rodportion 220 also has flexibleness in order not to in injure the patient.In different specific embodiments, the support portion 210 hasflexibleness, but the rod portion 220 has few or even no flexibleness.Thus, it is easy to control the control portion 230 to move relative tothe rod portion 220. In a specific embodiment, the support portion 210has greater flexibleness than the rod portion 220.

Referring to FIG. 3 , there is shown a schematic view of the surgicalmedical device according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 3 , a surgical medical device 300comprises a support portion 310, rod portion 320, and control portion330 movable relative to rod portion 320. The control mechanism of thesurgical medical device 300 is the control portion 330 disposed on therod portion 320. The support portion 310 has a second support end 318.The control portion 330 is separably connected to the second support end318. (Thus, the control portion 330 is in contact with the secondsupport end 318.) In so doing, the control portion 330 can be easilytaken out of the human body. In another specific embodiment, the controlportion 330 is inseparably connected to the second support end 318. Inthe embodiment illustrated by FIG. 3 , owing to its movement relative tothe rod portion, the control portion 330 can stretch or contract a firststretch segment 314 of the support portion 310, a third stretch segment315 of the support portion 310, and a second stretch segment 316 of thesupport portion 310. For example, the control portion 330 pushes thesupport portion 310 in the direction 352 relative to the rod portion 320so as to stretch the first stretch segment 314, third stretch segment315 and second stretch segment 316. Alternatively, the control portion330 moves in the direction 354 relative to the rod portion 320 tocontract the first stretch segment 314, third stretch segment 315 andsecond stretch segment 316. In a specific embodiment, the second supportend 318 is connected to the rod portion 320 while moving relative to therod portion 320. In a specific embodiment, the support conducting wiresof the support portion 310 are fixed to each other by adhesion to formthe second support end 318, and an adhesive for use in the adhesionloses its fixation capability above a specific temperature, resulting inseparation of the support conducting wires of the support portion 310.Thus, the urologist can heat up the adhesive at any time in whatever wayto cause separation of the support conducting wires of the supportportion 310, thereby facilitating removal of the surgical medical device300 from the human body.

Referring to FIG. 4A, there is shown a schematic view of the surgicalmedical device according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 4A, a rod portion 420A has a rodspring portion 424A disposed between a first support end 417A and asecond support end 418A. When a first stretch segment 414A, thirdstretch segment 415A and second stretch segment 416A are each in astretched state, the rod spring portion 424A provides a tensionconducive to maintaining a first stretched volume of the first stretchsegment 414A, a second stretched volume of the second stretch segment416A, and/or a third stretched volume of the third stretch segment 415A.In different specific embodiments, the rod spring portion 424A isdisposed at any position between the first support end 417A and thesecond support end 418A as needed.

Referring to FIG. 4B, there is shown a schematic view of the surgicalmedical device according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 4B, a support conducting wire 411Bhas a support spring portion 417B, a support conducting wire 412B has asupport spring portion 418B, and a support conducting wire 413B has asupport spring portion 419B. The support spring portions 417B, 418B,419B are disposed between a first support end 462B and a second supportend 464B. When the first stretch segment 414B, third stretch segment415B and second stretch segment 416B are each in a stretched state, thesupport spring portions 417B, 418B, 419B provide a tension conducive tomaintaining a first stretched volume of the first stretch segment 414B,a second stretched volume of the second stretch segment 416B, and/or athird stretched volume of the third stretch segment 415B. In differentspecific embodiments, the support conducting wires 411B, 412B, 413B arediscrete support conducting wires or connected support conducting wires.In different specific embodiments, the support spring portions 417B,418B, 419B are disposed at any position between the first support end462B and second support end 464B as needed. In the embodimentillustrated by FIG. 4B, a rod portion 420B has a first release portion426B, second release portion 427B and third release portion 428B. Thefunctions of the first release portion 426B, second release portion 427Band third release portion 428B are described below.

Referring to FIG. 5 , there is shown a schematic view of the surgicalmedical device according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 5 , a second support end 518 of asupport portion 510 is connected to a control portion 530. The supportportion 510 has a spiral structure. Thus, owing to its rotation relativeto a rod portion 520, the control portion 530 can stretch or contract afirst stretch segment 514, third stretch segment 515 and second stretchsegment 516. For example, the control portion 530 stretches the firststretch segment 514, third stretch segment 515 and second stretchsegment 516 in the direction 552 relative to the rod portion 520 orcontracts the first stretch segment 514, third stretch segment 515 andsecond stretch segment 516 in the direction 554 relative to the rodportion 520.

Referring to FIG. 6 , there is shown a schematic view of the surgicalmedical device being used in surgery according to a specific embodimentof the disclosure. In the embodiment illustrated by FIG. 6 , when afirst stretch segment 614, third stretch segment 615 and second stretchsegment 616 of a support portion 610 is in a contracted state, asurgical medical device 600 is admitted into the human body via aurethra 699. Once the surgical medical device 600 arrives at itsdestination, the first stretch segment 614, third stretch segment 615and second stretch segment 616 stretch. At this point in time, the firststretch segment 614 is disposed in a bladder 691, the third stretchsegment 615 at a bladder neck 693, and the second stretch segment 616 ina prostate 695. Thus, during the time period in which the surgicalmedical device 600 is placed inside the human body, the third stretchsegment 615 gradually stretches (or partially cuts) the bladder neck693, and thus the diameter of the bladder neck 693 increases. In theembodiment illustrated by FIG. 6 , when the first stretch segment 614,third stretch segment 615 and second stretch segment 616 are each in astretched state, the first stretch segment 614 is of a larger stretchedvolume than the third stretch segment 615, and the second stretchsegment 616 is of a larger stretched volume than the third stretchsegment 615. Thus, during the time period in which the surgical medicaldevice 600 is placed inside the human body, when the support portion 610slides toward the urethra 699 or is subjected to a force applied in thedirection toward the urethra 699, the first stretch segment 614 insidethe bladder 691 presses against the bladder 691 to thereby prevent thesecond stretch segment 616 from coming into contact with a sphincter 697to stretch it. When the support portion 610 slides toward the bladder691 or is subjected to a force applied in the direction toward thebladder 691, the second stretch segment 616 inside the prostate 695presses against the prostate 695 to thereby prevent the support portion610 from sliding toward the bladder 691 to a wrong position. FIG. 6 onlyserves illustrative purposes; during surgery, the bladder neck may havea larger or smaller diameter, and the bladder or prostate may be biggeror smaller in size. The urologist can choose surgical medical devices ofdifferent sizes according to the diameter of the bladder neck, thelength of the bladder neck, the size of the bladder, and/or the size ofthe prostate.

In a specific embodiment, the third stretch segment 615 exerts apressure ranging from 30 mmHg (millimeter of mercury) to 200 mmHg on thebladder neck 693, and thus blood vessels (for example, capillaries) atthe bladder neck 693 are compressed, thereby allowing the bladder neck693 to be stretched (or partially cut) gradually. In different specificembodiments, the pressure which the third stretch segment 615 exerts onthe bladder neck 693 is substantially equal to 30 mmHg, 50 mmHg, or 100mmHg; but the disclosure is not limited thereto. In a specificembodiment, the support portion 610 of the surgical medical device 600is configured to have flexibleness, and thus the pressure exerted by thethird stretch segment 615 of the support portion 610 on a target lesion(for example, the bladder neck) does not exceed a predetermined pressurethreshold; the pressure threshold may be set to any level as needed, forexample, 30 mmHg or 200 mmHg, but the disclosure is not limited thereto.

Referring to FIG. 7 , there is shown a schematic view of a surgicalmedical system according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 7 , a surgical medical system 700comprises a surgical medical device 710, containing device 720,cystoscope device 730 and injection device 740. The containing device720 has a containing channel for receiving the surgical medical device710. The cystoscope device 730 connects to the containing device 720.The cystoscope device 730 obtains a surgical visual field through thecontaining channel. The injection device 740 connects to the containingdevice 720. The injection device 740 injects a liquid into a surgicallesion through the containing channel. When the surgical medical system700 is in a ready state, the surgical medical device 710 is at leastpartially received in the containing channel of the containing device720. The containing device has a trigger 722. When the trigger 722 istriggered, the surgical medical device 710 is at least partially pushedout of the containing channel. In a specific embodiment, a supportportion of the surgical medical device 710 is made of a memory alloy. Afirst stretch segment 714, third stretch segment 715 and second stretchsegment 716 of the surgical medical device 710 are in a plastic statewhen below a first temperature, and in a stretched state when above asecond temperature. The injection device 740 connects to a regulationdevice. The injection device 740 injects liquids of differenttemperatures into a surgical lesion through the regulation device. Thus,the injection of the liquids of different temperatures enables the firststretch segment 714, third stretch segment 715 and second stretchsegment 716 to be in a plastic state or a stretched state.

Referring to FIG. 8A through FIG. 8C, there are shown schematic views ofthe surgical medical system according to a specific embodiment of thedisclosure. In the embodiment illustrated by FIG. 8A through FIG. 8C, acontaining device 820 has a three-stage triggering mechanism. When atrigger 822 is triggered in the first instance (see FIG. 8A), a surgicalmedical system 800 is in a first started state; thus, the containingdevice 820 pushes a surgical medical device 810 out partially, and inconsequence a first stretch segment 814 of the surgical medical device810 is pushed out of the containing channel. When the trigger 822 istriggered in the second instance (see FIG. 8B), the surgical medicalsystem 800 is in a second started state; thus, the containing device 820pushes the surgical medical device 810 out partially, and in consequencea third stretch segment 815 of the surgical medical device 810 is pushedout of the containing channel. When the trigger 822 is triggered in thethird instance (see FIG. 8C), the surgical medical system 800 is in athird started state; thus, the containing device 820 pushes the surgicalmedical device 810 out, and in consequence a second stretch segment 816of the surgical medical device 810 is pushed out of the containingchannel. In a specific embodiment, the containing device 820 has asnap-engaging portion in the containing channel and is snap-engaged witha first release portion, second release portion or third release portionof the surgical medical device 810 through the snap-engaging portion,thereby allowing the surgical medical system 800 to be in a firststarted state, second started state or third started state,respectively. The first release portion, second release portion andthird release portion are arranged in a way, for example, shown in FIG.4B (see the first release portion 426B, second release portion 427B andthird release portion 428B shown in FIG. 4B).

Referring to FIG. 9 , there is shown a schematic view of the surgicalmedical device according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 9 , a surgical medical device 900comprises a support portion 910. The support portion 910 has a firststretch segment 914, third stretch segment 915 and second stretchsegment 916. The third stretch segment 915 is disposed between the firststretch segment 914 and second stretch segment 916. The surgical medicaldevice 900 has a control mechanism. The surgical medical device 900stretches or contracts the first stretch segment 914, third stretchsegment 915 and second stretch segment 916 by the control mechanism.Preferably, when the first stretch segment 914, third stretch segment915 and second stretch segment 916 are each in a stretched state, thefirst stretch segment 914 is of a larger stretched volume than the thirdstretch segment 915, and the second stretch segment 916 is of a largerstretched volume than the third stretch segment 915. Preferably, thefirst stretch segment 914 has arcuate ends 917, 918, 919 for preventingthe insertion of the first stretch segment 914 into the human body fromcausing injuries, such as perforation, to the human body. Preferably,the second stretch segment 916 has folding auxiliary portions 911, 912,913 which, coupled with a folding device, are effective in folding andremoving the surgical medical device 900 out of the human body. Thefolding auxiliary portions 911, 912, 913 are described in detail later.Alternatively, the support portion 910 comprises one support conductingwire as needed or comprises a plurality of support conducting wires asneeded. At least two of the ends 917, 918, 919 of the first stretchsegment 914 are in communication with each other to thereby take on aspecific shape (for example, the arcuate shape of the first stretchsegment 114 in FIG. 1 ). The at least two ends 917, 918, 919 incommunication with each other are not necessarily in arcuate shape butmay be in any other shapes as needed.

In a specific embodiment, when the surgical medical device 900 is placedin the human body, the first stretch segment 914 is disposed in thebladder, the third stretch segment 915 at the bladder neck, and thesecond stretch segment 916 in the prostate. Thus, during the time periodin which the surgical medical device 900 is placed inside the humanbody, the third stretch segment 915 gradually stretches (or partiallycuts) the bladder neck, and thus the diameter of the bladder neckincreases. Thus, during the time period in which the surgical medicaldevice 900 is placed in the human body, when the support portion 910slides toward the urethra or is subjected to a force applied in thedirection toward the urethra, the first stretch segment 914 in thebladder presses against the bladder to thereby prevent the secondstretch segment 916 from coming into contact with the sphincter tostretch it. When the support portion 910 slides toward the bladder or issubjected to a force applied in the direction toward the bladder, thesecond stretch segment 916 inside the prostate presses against theprostate to thereby prevent the support portion 910 from sliding towardthe bladder to a wrong position. FIG. 9 only serves illustrativepurposes; the stretched volumes of the first stretch segment 914, thirdstretch segment 915, and second stretch segment 916 may be larger orsmaller as needed; for example, the stretched volumes of the firststretch segment 914 and second stretch segment 916 may be larger, or thestretched volume of the third stretch segment 915 may be smaller.

In a specific embodiment, the third stretch segment 915 exerts apressure ranging from 30 mmHg to 200 mmHg on the bladder neck, and thusblood vessels (for example, capillaries) at the bladder neck arecompressed, thereby allowing the bladder neck to be stretched (orpartially cut) gradually. In different specific embodiments, thepressure which the third stretch segment 915 exerts on the bladder neckis substantially equal to 30 mmHg, 50 mmHg, or 100 mmHg; but thedisclosure is not limited thereto.

In a specific embodiment, the support portion 910 is made of a memoryalloy. The control mechanism of the surgical medical device 900 is in aplastic state when the first stretch segment 914, third stretch segment915 and second stretch segment 916 are below a first temperature, and ina stretched state when above a second temperature. When the firststretch segment 914, third stretch segment 915 and second stretchsegment 916 are in a plastic state and are subjected to a compressingexternal force, the stretched volume of the first stretch segment 914,the stretched volume of the third stretch segment 915, and the stretchedvolume of the second stretch segment 916 decrease. In a specificembodiment, the first temperature is 20 degrees, and the secondtemperature is 35 degrees. In different specific embodiments, the firsttemperature and second temperature are set to any other temperatures asneeded.

Referring to FIG. 10 , there is shown a schematic view of a foldingdevice for folding the surgical medical device according to a specificembodiment of the disclosure. In the embodiment illustrated by FIG. 10 ,folding auxiliary portions 1011, 1012, 1013 are disposed at the secondstretch segment of a surgical medical device 1000. A folding device 1200comprises a tubular portion 1210 and a plurality of folding supports1220, 1230, 1240. The respective ends of the folding supports 1220,1230, 1240 have engaging ends 1222, 1232, 1242, respectively. Thefolding supports 1220, 1230, 1240 may be admitted into the tubularportion 1210 or at least partially protruded from the tubular portion1210.

The process of folding the surgical medical device 1000 into the tubularportion 1210 entails inserting the folding device 1200 into the humanbody via the urethra until the folding device 1200 reaches itsdestination, protruding the folding supports 1220, 1230, 1240 from thetubular portion 1210, allowing the engaging ends 1222, 1232, 1242 of thefolding supports 1220, 1230, 1240 to engage with the folding auxiliaryportions 1011, 1012, 1013 of the surgical medical device 1000 inside thehuman body, respectively, and moving the folding supports 1220, 1230,1240 along and into the tubular portion 1210. The surgical medicaldevice 1000 is folded into the tubular portion 1210, not only becausethe engaging ends 1222, 1232, 1242 are engaged with the foldingauxiliary portions 1011, 1012, 1013, respectively, but also because thefolding supports 1220, 1230, 1240 are admitted into the tubular portion1210. In a specific embodiment, after the engaging ends 1222, 1232, 1242have been engaged with the folding auxiliary portions 1011, 1012, 1013,respectively, it is feasible to directly pull the folding device 1200 inthe direction away from the human body in order to remove the surgicalmedical device 1000 from the human body without first folding thesurgical medical device 1000 into the tubular portion 1210 of thefolding device 1200.

Referring to FIG. 11A, there is shown a schematic view of the surgicalmedical system according to a specific embodiment of the disclosure. Inthe embodiment illustrated by FIG. 11A, a surgical medical system 1100comprises a containing device 1110 and surgical medical device (notshown). The containing device 1110 comprises a medical device containingportion 1112. The surgical medical device is at least partially receivedin the medical device containing portion. When the surgical medicaldevice is at least partially received in the medical device containingportion, the surgical medical device is in a ready state. Preferably,the medical device containing portion 1112 is demountably mounted at anend of the containing device 1110. Alternatively, the medical devicecontaining portion 1112 is part of the containing device 1110. In aspecific embodiment, the surgical medical system 1100 further comprisesan endoscope device (for example, cystoscope device) and/or injectiondevice. The endoscope device is connected to the containing device 1110or disposed in the containing channel of the containing device 1110. Theendoscope device obtains a surgical visual field through the containingchannel. Preferably, the containing channel of the containing device1110 and the interior of the medical device containing portion are incommunication with each other. The containing channel of the containingdevice 1110 extends and connects to an outlet 1114A of the medicaldevice containing portion 1112.

In the embodiment illustrated by FIG. 11A, when the surgical medicaldevice is in a folded state (also known as “contracted state”), thesurgical medical device is at least partially placed in the medicaldevice containing portion 1112 (for example, by inserting the surgicalmedical device into the medical device containing portion 1112 via theoutlet 1114A at the top of the medical device containing portion 1112.)For example, when the surgical medical device is in the plastic state,the surgical medical device is compressed and shrunken, and then thesurgical medical device is at least partially placed in the medicaldevice containing portion 1112. In a specific embodiment, the outlet ofthe medical device containing portion is a lateral communication outlet.The lateral communication outlet comprises a top outlet and a lateraloutlet which are in communication with each other and is exemplified bya lateral communication outlet 1114B shown in FIG. 11B. The lateralcommunication outlet prevents unnecessary displacement of the surgicalmedical device in the course of removal of the medical device containingportion. In the course of its gradual removal from the medical devicecontaining portion and its gradual stretching, the surgical medicaldevice is likely to rapidly slide under a stretching force, via theoutlet, out or into the medical device containing portion, and inconsequence the surgical medical device is unlikely to be positionedcorrectly. Thus, in some embodiments, the outlet is a lateralcommunication outlet in order to prevent the aforesaid unnecessary rapiddisplacement.
